LAB GUIDE

Installation Type - SPLAT Checkpoint Installation is accomplished in multiple ways which includes Installing Checkpoint on Secure Platform, on Windows Operating System or on Nokia Hardware. Here we discuss the SPLAT (Secure Platform) Installation in a Step by Step process. On the machine where SP

Once you hit Enter the Installation process starts,

Use Tab key to select OK and hit enter,

Language in which Checkpoint needs to be installed is selected, here we select US (i.e. English)

Select OK and hit enter,

Checkpoint will start Formatting process of the machine’s Hard Drive, select OK and Hit Enter

Checkpoint has finished copying files on the Hard Drive, select OK and hit enter

Firewall will reboot and get you to the login screen,

First time login will use default Username and Password as below: Username: admin Password: admin

Open a Browser and launch the Web User GUI login page

After accepting the license agreement, login page comes up. Use the credentials created on the first time CLI login

Click next,

Click on the eth1 which we want to use as external interface and assign it an ip address

Once IP address is assigned to eht1, click next to continue configuration

Assign a Default route address for the firewall as below

Once ip address is entered, click on apply

Default route will be listed in the Routing table

Entering the DNS server information, Hostname of the Firewall and selecting the Management interface

Here we go for manual settings, NTP server can also be used for this purpose,

STATIC NAT To configure the STATIC NAT we require two nodes, one for the available public ip and another for the internal private ip of the Server (It can be any server like web, ftp, smtp etc...) On the left panel, Network Objects tab which is the first tab, right click on Nodes and select Host

Specify the name and ip address of the Server in use

On the NAT tab select Add Automatic Translation rules and specify the free Public address available,

Creat another Node in the same way as explained above,

Both the newly created nodes appear under the Nodes option

Rules should look like as shown below,

Static NAT for different Services

To perform Static NAT behind a single Public IP to different Private IP’s in a DMZ based upon the

services, we look at a sample configuration. In the below example, Go to NAT tab and add manual static

NAT rules according to the requirement.

Below example shows the Manual Hide NAT configuration, once you drag and drop the public server

object a window pops up asking to choose from the two options as shown below,

The Manual Hide NAT rule looks as below,

Authentication Select the Users tab from the left panel, right click on the Users container and select the new user and the default option

Select the service according to the authentication scheme and on the actions tab right click go to Legacy and select User Auth

Once rule is created, under Action double click on the User Auth select All Servers. Install the Policy to enable authentication.

External authentication:

We look at the example of enabling authentication using TACACS+ server as an external source. To create TACACS+ server on checkpoint first we create a Node . In the Network Objects tab create a node, defining the IP address of the TACACS+ server

Once done you will see TACACS+ server listed under Nodes option

Go to Server and OPSEC Applications tab, right click on the Servers option, select New and click on TACACS

Specify a name for the TACACS+ Server and for the Host option select the node that was created to specify the TACACS+ Server and select the type as TACACS+ and mention the secret key

A new window opens up,

Go to Authentication tab and select TACACS as the Authentication Scheme:

Create a General user on the left panel users, we already have a user created, right click the username and click on Edit

A window opens up, go to Authentication and select the Authentication scheme as TACACS and select the TACACS Server

Creating Rule: Create the rule as explained in the User authentication process, Select the service according to the authentication scheme and on the actions tab right click go to Legacy and select Session Auth

The rule should look as below,

Now we go got client auth, here we need a client software to be installed on the users machine for auth to happen, the configuration required to setup will be same as explained above, the action tab will be having Client Auth in it. To see the sub configuration under the Client auth you need to double click on it and configure accordingly.
